feat(TextMatch): upgrade dom-testing-library

- Changes queries to default to exact string matching
- Can opt-in to fuzzy matches by passing { exact: true } as the last arg
- Queries that search inner text collapse whitespace
  (queryByText, queryByLabelText)

Closes #76

BREAKING CHANGE: Strings are considered to be an exact match now. You can opt-into fuzzy matching, but it's recommended to use a regex instead.
