Description

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.

Testing Done


Created Docker container form easybe/alpine-reviewboard:wip
Sucessfully added an SVN repository not requiring authentication
