Fix public SVN repository support with Subvertpy
Review Request #10087 — Created July 16, 2018 and submitted
When using Subvertpy as an SCM backend, adding a repository not requiring authentication would cause a segfault. This is due to a call to `subvertpy.ra.Auth.auth.get_parameter()` although the parameter was not previously set.
