Cannot remove or install flows that have a period "." in their name

The web interface allows for creation of a flow that has a period in its name. For example:
a.b
But then the user is unable to install or remove the flow using the interface. I am able to remove the flow using the REST API directly.

To reproduce:
1) Create a flow named: a.b
2) Try to remove the flow

Expected behavior:
Either do not allow creation of flows with a period in their name, or allow removal of these flows.
