(#2435) - disable saucelabs for now

*in the distance, the sound of a bugler mournfully
playing Taps can be heard*
(#2447) - link pouchdb-server's pouchdb to us in travis

Travis seems to be an unusual environment where the
immediate dependents of a module that depend on that module
are not automatically symlinked to it.  So this fix is to
only do it in Travis.

This is required to unblock #2442.
