Subject: [PATCH] Allow jest script to run on individual files

This allows the jest test script for the enterprise_search plugin
to run on files, and well as directories.

Previously, a trailing slash was always appended, whether it was
a file name, or a directory. It now maintains whatever a user originally
inputted.
