create_workspace_on_output: Prevent duplicate workspace nums

Browse Source 
When going through the `binding_workspace_names` to prioritize
user-specified names, we only check if the workspace exists, not the
workspace number. If the user specified a `bindsym … workspace number X`
directive, then it is appended in `binding_workspace_names` and a
workspace is created using that number even though from the POV of a
user that uses numbers to change workspaces, that workspace already
exists.

In similar code here:
1d9160f2d2/src/workspace.c (L997)
we do the check.

Fixes #4238
