Mac: Sometimes see empty parens in Open With menu

[redmunds]

This was introduced with these pull requests: #2653, adobe/brackets-shell#190

Recipe

1. In Mac File Chooser, right-click on a file
2. Select "Open With"
3. In sub-menu, notice that Brackets is now listed

Results
For some files, empty parens are displayed next to Brackets.

This seems to depend on what the default app to open the particular file type, so test with files targetted by Brackets: .htm, .html, .css, .js, .php. .json, etc.
