tests: fix regexp for main/installation test

The updated regex should work for a situation where we check for a plug/slot connection of a snap that is not first on the connection
list - it is listed alphabetically.

E.g.:

:network-bind core,tpm2

The old version would return a failure as it started matching with spaces at the beginning. The new version understands that there might be a snap name too.
