Directories ending with a space cannot be viewed in the Source tab

Summary

If a directory ends with a space character, that directory fails to load in the Source tab.

Steps to Reproduce

1. Create a directory ending with a space, and push it to a repository.
2. Navigate to the Source of that repository in Bitbucket Server, and navigate to the directory that ends with a space.

Expected Results

The contents of the directory are shown.

Actual Results

The following error is shown to the user:

The path "test_dir/another_test_dir/directory end space" does not exist at revision "refs/heads/master"

Notes

The error does not show a trailing space in the directory name, so it appears the space is trimmed out, causing the path to be invalid.

Workaround

If a trailing slash is added to the URL pointing to this directory, the contents load successfully.
