Change Details

`wdio-mocha-framework` is set correctly to 0.6.4, which brings in `wdio-sync` at 0.7.3 and so `fibers` at v3.x (which works), but `wdio-cucumber-framework` is pinned to 1.1.1, which pins `wdio-sync` at 0.7.0, which pins to `fibers` v2.x, which then breaks.

The `wmf-quibble-core-vendor-mysql-hhvm-docker` job fails with error: gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable. `wdio-mocha-framework` is set correctly to 0.6.4, which brings in `wdio-sync` at 0.7.3 and so `fibers` at v3.x (which works), but `wdio-cucumber-framework` is pinned to 1.1.1, which pins `wdio-sync` at 0.7.0, which pins to `fibers` v2.x, which then breaks.
