[wasm][debugger] Firefox tests cancelled or throwing KeyNotFoundException - test files cannot be found

[ilonatommy]

Sample Run.

Around 80 tests on Firefox failing on CI and locally. There are different messages:

• Test file not found, failing assert: e.g. MiscTests.CheckThatAllSourcesAreSent

Assert.Contains() Failure
Not found: dotnet://debugger-test.dll/debugger-test.cs
In value:  ValueCollection<String, String> ["debugger-driver.html", "debugger-driver.html", "debugger-driver.html", "debugger-driver.html", "debugger-driver.html", ...]

• Test not found, throwing exception, e.g. DebuggerTests.ArrayTests.InspectGenericValueTypeArrayLocals

System.Collections.Generic.KeyNotFoundException : The given key 'dotnet://debugger-test.dll/debugger-array-test.cs' was not present in the dictionary.

• Cannot set a breakpoint = test cancelled, e.g DebuggerTests.SteppingTests.BreakOnAwaitThenResumeToNextBreakpoint

 Failed DebuggerTests.AsyncTests.AsyncLocalsInNestedContinueWithStaticBlock [30 ms]
  Error Message:
   System.Threading.Tasks.TaskCanceledException : A task was canceled.
  Stack Trace:
     at DebuggerTests.DebuggerTestFirefox.SetBreakpointInMethod(String assembly, String type, String method, Int32 lineOffset, Int32 col, String condition) in /_/src/mono/wasm/debugger/DebuggerTestSuite/DebuggerTestFirefox.cs:line 388
   at DebuggerTests.DebuggerTestBase.CheckInspectLocalsAtBreakpointSite(String type, String method, Int32 line_offset, String bp_function_name, String eval_expression, Func`2 locals_fn, Func`2 wait_for_event_fn, Boolean use_cfo, String assembly, Int32 col) in /_/src/mono/wasm/debugger/DebuggerTestSuite/DebuggerTestBase.cs:line 231
   at DebuggerTests.AsyncTests.AsyncLocalsInNestedContinueWithStaticBlock() in /_/src/mono/wasm/debugger/DebuggerTestSuite/AsyncTests.cs:line 66

• CallToEvaluateLocal name missmatch. e.g. InspectLocalsUsingClassFromLibraryUsingDebugTypeFull

  Failed DebuggerTests.MiscTests.InspectLocalsUsingClassFromLibraryUsingDebugTypeFull
  Error Message:
   [_debugger_test__DebugTypeFull_CallToEvaluateLocal]

Expected: CallToEvaluateLocal
Actual:   _debugger_test__DebugTypeFull_CallToEvaluateLocal

Introduced by #69072 and resetting before 56e58d3 fixes the issue.
