File filtering in the source browser fails if the repository's file tree is too large to fetch

Issue Summary

Repository with deep tree directories will cause the filtering feature unusable due to the following endpoint hitting Error 555 !api/internal/repositories/<workspaceID>/<Slug>/tree/<hash>/?no_size=1

Steps to Reproduce

1. Click on the filter files search box.
2. You get the error message "There was an error filtering files. Please try again later."

Expected Results

File filtering should work fine and display the file that is searched.

Actual Results

We get the error message "There was an error filtering files. Please try again later."

Workaround

The only workaround at the moment is to browse the repository on the local filesystem, find the path of the file or directory that you would like to view in the Bitbucket UI and update the URL manually.(example: https://bitbucket.org/bbtest/bbtestrepo/src/<ref>/<path_to_file_or_directory>
