Allows setting fixture_path to a Pathname
Change Standard error when is required bcrypt-ruby and fails
Removed unused loop variable
Delete failing test

I don't think this is testing anything useful, and the test code is
exceedingly brittle. It is broken since
34c7e73c1def1312e59ef1f334586ff2f668246e because the test code makes
assumptions about the implementation of PostgreSQLAdapter#active? which
are incorrect after the commit.

I could fix this test but it would be even more brittle (by stubbing the
underlying @connection.connect_poll) and it doesn't test any complex
logic. I conclude that it's not worth it.
Send SIGTERM, not SIGQUIT.

SIGTERM is the correct signal for a graceful exit.

This will hopefully resolve #9761.

StringIO is not required by default in JRuby
test-case to prevent resetting associations when preloading twice.

Conflicts:

	activerecord/lib/active_record/associations/preloader/through_association.rb
	activerecord/test/cases/associations/eager_test.rb
Don't kill the console

Use the "quit" command instead. This seems to prevents some weirdness on
OS X. See #9761.
Remove exception variable from rescue block

Just raising from the rescue block will re-raise the exception, so the
variable is not necessary.
