Adds test for presence of store using integration: true in moduleForModel

[nikz]

Hi team!

I'm having a bit of trouble with the latest version of ember-test-helpers. It looks like there was a regression with integration: true somewhere that means container.lookup("store:main") is returning undefined. 😿

I've added a failing test for this, and I'm working on a fix at the moment (although any pointers as to the right direction are greatly appreciated!)

Thanks,

Nik

A fix seems to be already on it's way #49.
I'm also waiting to be able to pull it but a temp. workaround is calling DS._setupContainer(this.registry);

@WooDzu awesome! thanks for that.

[rwjblue]

Thank you for the test!! I'll pull it into my branch in #49 and confirm all is working properly there...

[rwjblue]

I pulled the test into #49 (and removed the equal(123, store) assertion), I'm going to close this PR in favor of that one.

Thank you again for taking the time to submit a failing test!

@rwjblue no worries, sorry for leaving in the random extra assertion :)
