Juan Tejada 3a49bfe448 fix(specs) Fix Spellchecker tests
Summary:
Previously, these tests were mostly testing the library itself, instead
of our code. The library performed expensive operations and caused the
test to time out more often than not

This commit makes it so we test our code, mock out any calls to side
effects, and removes a line that was overriding our jasmine timeout

Test Plan: unit
