Starter version: 0.14.14.

If a folder where one tries to run ArangoDB through Starter has bogus (i.e. random stuff) .local file which is picked by arangod binary as the first possible conf by default (if no DEB was installed), Starter is unable to launch server with

2020-06-01T19:43:15+02:00 |INFO| Starting arangodb version 0.14.14, build 598e7d7 component=arangodb
2020-06-01T19:43:16+02:00 |INFO| Wait on 6472 returned component=arangodb exit-status=1 trap-cause=-1
2020-06-01T19:43:16+02:00 |FATA| Failed to run service component=arangodb error="Failed to detect database features: No server-version found in ''"

In order to prevent this Starter should provide none configuration to arangod binary during version check.
