Fix 412 precondition error from selecting branch repeatedly.

Reload the productseries after setting the branch.

== Pre-implementation notes ==
None

== Implementation details ==
None

== Tests ==
None

Go to the +sharing-details page for a sourcepackage. Select a branch. Then select another branch. The second time should not give a 412 precondition failed error.
