Add a method to osmoutils for having a function write to state if no err (#872)

@antstalepresh made a neat method for doing this in a few places in the
superfluid epoch logic. This just refactors it to a standalone method in
osmoutils.

Furthermore, this PR also renames osmotestutils -> osmoutils, which
is a change I've wanted to make for a while.
