pin mongoid to a specific version

https://github.com/ahoward/mongoid-grid_fs/pull/31 mongoid commit
cc7a0e709066aff444bc21cd9826e1568603934d broke mongoid-grid_fs so
we're pinning it to the commit before that.  we can un-pin mongoid
when mongoid-grid_fs becomes compatible with mongoid master.
remove ruby 1.9.2 from list of supported rubies

We evidently removed 1.9.2 from the set of rubies that we run in
Travis, so we shouldn't claim that we test with it.
pin rspec-core to a specific version

we were getting strange behavior only in jruby with rspec-core 2.14.6.
All of the tests would pass but the rake task would return 1 and cause
the Travis build to fail, for example
https://travis-ci.org/sferik/rails_admin/jobs/12765829.  On my machine
it failed intermittently but on Travis it was consistent.  2.14.5
works consistently so for now we'll pin it to that version.
Workaround for jruby rake issue. Refs #1804
