Stop if provider dependency fails

[tsloughter]

An example is common_test provider which still runs even if the compile provider finds errors.

I'm trying to reproduce this, but can't get it to get onto common test.

[omarkj]

Rebar3 does not continue onto the next provider if compile fails, but it does continue if the compile has some warnings. This is behavior that I expect.

[tsloughter]

Nm! This was me being stupid and thinking warnings as erors was on.

Thanks.
