cot edit-properties interactive is broken in v1.2.2

[glennmatthews]

In v1.2.2 the interactive edit-properties mode is no longer entered if no properties are given on the command line:

> cot edit-properties -o foo.ovf COT/tests/input.ovf 
    INFO: Loading 'COT/tests/input.ovf' as OVF
    INFO: OVF version is 1.x
    INFO: OVF product class None --> platform GenericPlatform
Overwrite existing file foo.ovf? [y] y
    INFO: Writing out to file foo.ovf
    INFO: Copying input.vmdk to /Users/glmatthe/Documents/OVF_Tools/cot-public/cot
    INFO: Copying input.iso to /Users/glmatthe/Documents/OVF_Tools/cot-public/cot

In v1.2.1 the functionality still works:

> cot edit-properties -o foo.ovf COT/tests/input.ovf 
    INFO: Loading 'COT/tests/input.ovf' as OVF
    INFO: OVF version is 1.x
    INFO: OVF product class None --> platform GenericPlatform
