v4 is not working for select environments

[NullVoxPopuli]

Placeholder issue to have details later

Some discussion: #206

[ef4]

This is caused by emberjs/babel-plugin-ember-template-compilation#30

[NullVoxPopuli]

This is resolved.

For folks who run in to any issues with v4, make sure that your lockfile states that babel-plugin-ember-template-compilation is at least 2.2.1.
if it's not, delete the entry in the lockfile and re-run your package manager -- that should update it.

To aid future searchers like me: the advice in this ticket fixed an issue for me when using ember-template-imports v4 in a v1 addon, imports referenced within template tags were removed / elided / missing.
