get ember-try working again

[tomwayson]

I have no idea what the fuck happened in #76 but the whole stack of cards came crashing down.

I could not replicate the template lint errors locally.

I can't run ember-try locally. I can't even really run ember t locally unless I supply the -s parameter, otherwise it "fails" w/ this error at the command line:

➜  ember-esri-loader git:(f/updating-js-api) ember t

Testem finished with non-zero exit code. Tests failed.

Thing is, the tests really pass:

It's like the command lost the connection to FireFox.

Here's another riddle - why are tests running in FF locally anyway?

ember-esri-loader/testem.js

Line 8 in 8489e01

'Chrome'

yarn run lint:hbs and ember t -s both pass for me locally, so 🤷‍♂
