Simplify createComponent() types in tests (#535)

The `...config` in particular was causing type issues when upgrading
@vue/test-utils in #492; and while that pull request is also blocked for
other reasons, I think we can make our lives easier by simplifying these
types. Callers of this method (which is local to this one test file)
only pass in props and/or global.provide, so we can just specify the
types for those members instead of full ComponentOptions; the Props type
from LemmaInput is just duplicated, since I think that’s simpler than
trying to get it back out of the full/exported LemmaInput type again.
