Update/tests with plugin uninstall commands

[circlecube]

Proposed changes

This updates a support method used in cypress tests. Currently, it uninstalls all plugins except those listed in the exclude list. I'm updating it to only uninstall the plugins that the test installs (Woo and the YITH payment plugins that are automatically installed with it). The module shouldn't have to keep a list of plugins to exclude.

I ran into issues with the bluehost plugin migration where even though the build slug will not be changed, in the testing env it can show up differently. This change fixes those issues and also will be more stable. The tests should clean up after themselves and not attempt to uninstall everything anyways - that approach is more brute force than we needed (and I think I'm to blame for it).

I see Crazy Domains tests are failing, but it is the coming soon tests. They should be updated by this PR newfold-labs/wp-module-coming-soon#44 when it gets merged and updated in that plugin. Otherwise things look good for tests.
