Fix quick access path search and autocomplete text

[jjw24]

• Fix directory path search when triggered from quick access
• Fix autocomplete text when both path and search action keywords are disabled
• Added unit tests

Note: if both path and search action keywords are disabled, selecting the result will open the folder instead of navigating to the path.

Tested:

• Select folder result listed via Quick Access will navigate to the path with search action keyword when both search and path search action keywords are enabled or only search action keyword is enabled
• When search action keyword is disabled and path search is enabled, selecting result will navigate to the path with path search action keyword
• When both path and search action keywords are disabled, selecting result will open the folder instead
• When both path and search action keywords are disabled, autocomplete will autocomplete with the title of the folder
• Using content search will navigate to folder/file paths correctly via autocomplete or selecting folder result
