Bug 992464 - Authorization token needs to raise when checking eventual consistency

Was using .first which returns nil
Use marker_present for conformity
Bug 994922

Warn user of supervisor control when we detect 'hot_deploy' marker.

When the hot_deploy marker is present, stop nor start is invoked, so
we need to check the presence of the marker in a different way.

Notice that the first time we push 'hot_deploy' marker, the stop cycle
will not warn that it detected the marker (because it doesn't exist on
the gear).
Fix typo
Follow up fix for Bug 970150

It turns out that 6400c02 wasn't really working.
The inner `if` clause, `$?` is `0` no matter what the result from
the app name check, so that any app name would fail for Rails.

This fixes that.
