Title: Don't crash cover on insufficient_vnodes_available

* Change `calc_plan` to return error-tuple rather than match it and
throw it.

* Check for error-tuple when generating cached coverage plans and
store undefined. That will prevent cover server from crashing.

* Check for error-tuple during search request and return proper error
msg to user.
