* Adds a is-empty/not-empty for strings

What the UI calls "is empty" / "not empty" right now is a null check,
not a null and "" string check.

This adds is-empty / not-empty operators in the query processor, and
reworks the UI to use those. Any existing query that previously used the
is-null / not-null operators will show (as "Is null" / "Not null") but
any newly made queries will not be able to select "Is null" / "Not null"
for text type fields.

This will allow backwards compatibility with existing questions, while
promoting use of the new "is-empty"/"not-empty" operators.
Added Cypress test to make sure the proper operators show up when asking
questions

Update memoize util to allow variable number of args

Resolves #5299

* Update eslint

Updates eslint, babel and plugins to the latest compatible versions

Drops the 'no-color-literals' parameter which doesn't exist (looks like
it's actually part of eslint-plugin-react-native which we don't use)

adding a dirlocal to make sure js2-mode doesn't confuse you with type
errors that aren't actually errors because of flowtype and such
