[Bug]: win_lgpo_reg: value name with period causes state failure

[dafyddj]

What happened?

A lgpo_reg.value_present state that previously worked on versions up to v3006.14 now results in failure.
The value name has a period/dot in it.
Example:

# salt DESKTOP-G7IDEEE -t 10 state.single lgpo_reg.value_present SCRNSAVE.EXE key='Software\Policies\Microsoft\Windows\Control Panel\Desktop' v_data=screensaver v_type=REG_SZ policy_class=User

Note: the state is actually applied successfully but the return result is False.
