In order to display the related changes we need to know the current
revision. Although the current revision is requested it can happen
that it is not returned by the server. In this case the UI failed to
display the related changes for that tab (it showed the progress bar
and the 'Working...' label never disappeared). Fix the code so that we
can handle changes for which the current revision is not set. These
changes will simply be ignored.
Ie465a182267c39d7fed07921c2271fa5544a8ed2 is an example for a change
which doesn't return a current revision for me although I requested
it. For Id20e567e5c5d5b3d851ca5cda9bde01ac01c9967 it can be seen how
the "Conflicts With" tab cannot display the conflicting changes due to
that change.
