* 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

Using version 220 of `jest-localstorage-mock` required that we upgrade
our version of NodeJS from our previous minimum of 6.11.3. To support
that, this commit switches from the deprecated
`java:openjdk-8-jdk-alpine` docker image to the newer
`openjdk:8-jdk-alpine` image. This image is running Alpine version 3.8 which
has NodeJS 8.11.4 in it's repository. This also bumps the minimum
version of node in the packages.json file.
