chore(lint): fix lint in v3 after v2.18.1 merge (#3667)

this commit fixes a lint error that is the result of the following
course of actions:
- https://github.com/ionic-team/stencil/pull/3621/files updated
  eslint-plugin-jest, which now errors on aliased mathers
- the changes in the aforementioned PR were pulled into the v3.0.0-dev
  branch
- the new lint rules didn't run on that branch until the merge, catching
  one violation in the v3 branch that wasn't in the v2 branch
