[TECHNICAL-SUPPORT] LPS-44153 Page layout template association cannot be changed if the current template is missing

Hey Tamás,

https://issues.liferay.com/browse/LPS-44153
We already use "getLayoutTemplate()" at several other places in the class, so I just applied the pattern. IMHO, users should be able to change the template association of a given layout, even if the currently assigned one is missing.
