Compute resource test connection enables password field
The fix from #13497 made the password always enabled, so that it does not get disabled after pw change followed by test connection trigger. This does not work in scenario, where user edits existing CR and hits test connection button. It keeps pw field enabled so if I click submit immediately, it fails since the password is empty. User either needs to specify the password again or click the disable button. While testing this I also realized that after testing connection for new CR, the enable/disable button is also displayed.
Regression caused in 1.18 but given the workaround, most likely not worth cherry-picking.
