Pull `podModulePrefix` from config/environment.js.

This brings using a custom pod prefix inline with the normal
`modulePrefix`.  If not defined (by default it isn't) then it will just
fallback to `modulePrefix` (this done
[here](https://github.com/stefanpenner/ember-jj-abrams-resolver/blob/master/packages/ember-resolver/lib/core.js#L171)).
[windows] - make configPath test work on windows
[windows] split output on unix line endings

Looks like inquirer which is used by ui for creating prompts uses unix
line endings instead of enviornment specific. This causes the tests that
split the output to run assertions to fail.

Switched those specific tests to split on unix line endings as that split
the lines at the same place anyway and none of the regex are specific
enough to care about the extra `\r`

Exit non-zero with nice error if `ember test` runs nothing.
[windows] filterpattern test works on windows

This is the simplest fix to make the test pass. It raises the question of
wether the LiveReloadServer should normalize the slashes in the
filterPatterns so the same pattern can work on different OS. If not the
user would have to craft regex which aren't OS specific, or provided to
filters.
