fix(travis): deploy client on every push to master

Travis' `on` condition is an AND operation, so essentially in its
current configuration no client builds will be produced because
the build must be

1) from a merge to master AND
2) a tagged release

We have branching logic in `make prep-bintray-manifest` that will
deploy client builds to either deisci or to the deis org depending
on if the commit is from a tag or not, so we should deploy on
every PR so the deisci org is filled to the brim with cilent builds.
