Improve spec boot time and clean up logs

[voodoorai2000]

What

• Regenerate bin stubs
• Remove circular argument reference warning
• Run Coveralls only in Travis CI
• Remove default profiling

Why

• The new bin stubs bring down spec boot time from 10 seconds to 1
• Warnings are never pretty
• Running coveralls locally is not very efficient, build takes too long
• Profiling when running tests locally mainly clutters the log, we can reactivate it at any time to identify and refactor the longest running specs

Screenshots
