Revert MuonShowerInformationProducer back to legacy

[Dr15Jones]

MuonShowerInformationProducer was missed when we reverted all modules
using MuonDetLayerGeometry back to legacy to avoid thread safety
problems.

 * [new ref]                    -> merge-attempt
fatal: Couldn't find remote ref refs/pull/3550/head
Unexpected end of command stream

what's going on?

[Dr15Jones]

@ktf any ideas?

[Dr15Jones]

@nclopezo has the test for this been started?

[nclopezo]

Hi @Dr15Jones,

Yes, but I had troubles with git as well. I had to use the branch name for git cms-merge-topic and I will post the results by hand as soon as they finish.

When I do

git ls-remote official-cmssw

I only see c8bb0ba refs/pull/3555/merge
but not
refs/pull/3555/head

The same happens with #3550

Yesterday, when I made the pull requests, github had web server errors but the pull request appeared to go through.

for #3555 114a11a

tested in CMSSW_7_1_X_2014-04-29-0200
( test area sign361 pulls 3475 3529 3531 3550 3555 together)
no regressions here.
Still had to merge manually from Chris' branch

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_1_X IBs unless changes (tests are also fine). @nclopezo, @ktf can you please take care of it?
