STCOR-551 configure karma for v6 compatibility

[zburke]

There are some overlapping things going on here.

• stripes-webpack supports the new JSX transform that means we
  shouldn't have to import React ... any longer, but BigTest tests
  fail without it when using karma v4 (from stripes-cli v1.2).
• when using karma v6 (from stripes-cli v1.3), the karma config
  directives files and preprocessors cause test files not be found
  at all.

Bumping the stripes-cli dep (so we get karma v6) and cleaning up
karma.config.js (so it is v6 compatible, and more aligned with
configs in other repos) allows tests to run as they always did. Phew.
