fix: use own workspace endpoint instead of PROPFIND properties

With a lot of subdirectories the depth=1 PROPFIND will take quite a long time.
It has to look for workspace files in all the subdirectories.

Stop overloading the PROPFIND and rely on our own workspace endpoint
for that particular directory instead.
