Created a test that creates the WM instance and ensures the instance is
running. The test creates a custom socket and then cleans up the socket
file after completion.
Created a test that creates a WM instance, monitor instance, and
workpace. The tests checks to ensure that the expected workspace is
focused properly.
Included recommended fixes to ensure that the focus_workspace function
is used correctly and that the test accurately checks the workspaces
length, current workspace index, and switching to an existing workspace.
