MongoDB connector:
Issue:
[MongoDB
documentation](https://www.mongodb.com/docs/manual/reference/connection-string/)
states that characters `$ : / ? # [ ] @` must be percent encoded. URI
with password containing such special character will not be redacted.
Fix:
This fix removes usage of `unquote_plus` on password which allows
detected password to match with one inside URI and successfully replace
it.
Git connector:
Added very basic unit tests for repository filtering methods. Their
impact is rather minimal but showcases current limitation in
`is_file_type_supported` method.
