function FileDirectoryTest::testFileDestination

This will test the filepath for a destination based on passed flags and whether or not the file exists.

If a file exists, file_destination($destination, $replace) will either return:

• the existing filepath, if $replace is FILE_EXISTS_REPLACE
• a new filepath if FILE_EXISTS_RENAME
• an error (returning FALSE) if FILE_EXISTS_ERROR.

If the file doesn't currently exist, then it will simply return the filepath.
