Refactor test helpers (#1336)
* Refactor test helpers
* Combine common codes from `parse` and `build`, and dispatch using
`Mode`
* Remove `toNotBuild` and `toNotParse` and use `expect.not`
* Remove `Warning` and instead mock `console.warn`
* Add `expect.toHavePassed` and check whether parse/build succeeded
lazily
* Improve failed test `message`:
- Use color
- Print stack traces(excluding internals)
- Print diff
- Follow jest matcher output style
* Update helpers.js
* Remove toBeTruthy checks
getParsed throws an error if parsing fails.
* Used tagged literals
* Use .toHaveLength
* Use tagged literals
* Use to{Build,Parse}Like where possible
* Remove compareParseTree
* Use snapshot where possible
* Join into one line where <88 chars
* Revert console.warn() to throw an error
Merge `expectToWarn` to `expectKaTeX`, like
`expect.toFailWithParseError`
* Remove call to console.warn from stack traces
* Fix merge errors
* Remove `getTree`
* Move `_getBuilt` into `getBuilt`
* Move default settings and tagging literal support in to `getParsed`
and `getBuilt`
* Remove stack traces clean-up
* Remove `toHavePassed` matcher
* Extract `expected` string construction into `printExpectedResult`
