Remove double backslashes from file path when opening unsupported files.

Closes #1014

[shambhupatil]

I think CIs are failing because the file path should be displayed in quotes.

I think CIs are failing because the file path should be displayed in quotes.

Looks like it, yes. The failing test

1/1 Test #429: f3d::TestUnsupportedFileText .....***Failed  Required regular expression not found. Regex=[.*unsupportedFile.dummy" is not a file of a supported file format

is defined here: https://github.com/f3d-app/f3d/blob/6133d0fa6189061f9fea453441dfbe086ba95087/application/testing/CMakeLists.txt#L877

You'll have to either:

• change the code to output the quotes
• change the test to not expect the quotes

I can't tell you which one is the way to go but @mwestphal and @Meakk will

[mwestphal]

You need to update the test, but it's a bit unclear to me where the quote was coming from in the first place.

[shambhupatil]

Okay, I will look into why the quotes were there. Could you tell me how to update the tests?
