Fix TRIM_NEWLINES_AND_TRAILING_WHITESPACE_R regex bug

[mar4uk]

I found out if to pass to compiler string with consecutive \n in the middle of the text, then this replace doesn't work

`${input.replace(TRIM_NEWLINES_AND_TRAILING_WHITESPACE_R, '')}\n\n`,

There is an infinite loading. It happens only when the sequence of \n is longer than 25-30 symbols.

This bug was implemented in this commit bef82a5

I suppose that group inside the group in regex works very slow, that is why there is an infinite loading.

So in this PR I added the test of this case and simplified regex for TRIM_NEWLINES_AND_TRAILING_WHITESPACE_R
