@cypress/grep v6 doesn't respect tag negation

[joshuajtward]

Current behavior

Between versions 5.1.0 and 6.0.0 of @cypress/grep the negative tags (i.e. using -@myTag to exclude tests) has stopped working, and tagged tests are no longer being excluded

Desired behavior

Tag exclusion works as intended

Test code to reproduce

Add it('should not run', { tags: ['@tag']}, () => { expect(true).to.equal(false) }) to a new file

Run cypress with `CYPRESS_grepFilterSpecs=true CYPRESS_grepOmitFiltered=true CYPRESS_grepTags="-@tag"

The test should not be executed

This behavior is broken between 5.1.0 and 6.0.0

Hi @joshuajtward ,

The breaking change in @cypress/grep that necessitated the major version release was related to how the plugin is configured. It can no longer be configured directly via environment variables, and must be configured either with command line arguments (e.g., cypress run --expose grepTags="one,two") or via the cypress configuration file's expose key. Does this issue persist when the plugin is configured in this way?
