FileUtils.canonicalizeFolderPath() is confusing (now deprecated - need to remove)

[peterflynn]

This utility function "canonicalizes" paths by making sure paths pointing to folders don't end in a trailing slash. However, the canonical format of NativeFileSystem.DirectoryEntry (and thus most paths in the Brackets code), is the opposite of this -- directories always have a trailing slash.

Looking at references to this API, it appears to only be used by code related to Recent Projects. Perhaps we should clean up that code and then remove this API?

To me, low priority.

Reviewed.

This was deprecated as part of the FileSystem migration. Assigning to me to track eventually removing it (along with the other deprecated FS-related APIs - #6127).

@peterflynn This can be closed. The API was removed with #8992.
