When the repository form's code was moved to ES6, there were a couple of

regressions that broke the form's functionality.
First, the page was crashing when trying to set the help text. It was

attempting to use a variable that was no longer defined. We now just

pass the value originally set for that variable into the function that

needed it.
Second, a typo in a selector resulted in SCMTool-specific rows not being

hidden properly, causing some confusion when trying to configure a

hosting service.
This brings the repository form back to working order.

Created some repositories and switched between hosting services and

repository types. Everything appeared to behave as expected.
