Changing VLAN group scope type does not toggle selection fields correctly

[jeremystretch]

NetBox version

v3.0-beta2

Python version

3.7

Steps to Reproduce

1. Navigate to IPAM > VLAN Groups > Add
2. Select several different scope types and observe the selection fields below

Expected Behavior

Initially, none of the selection fields below scope type should be present. Once a scope type has been selected, only the relevant selection fields should be displayed.

For example, if the scope type has been set to "site," only the region, site group, and site fields should be visible.

Observed Behavior

Initially, all scope selection fields are visible instead of hidden. After selecting a scope type, the form widgets are hidden, however the parent form "rows" (with labels) are not.
