getLocale, getLayer: merge order

[dbauszus-glx]

The getLocale module method calls the mergeTemplates() method before the Roles.check() followed by Roles.objMerge().

The getLayer module method calls Roles.check() followed by Roles.objMerge() first before the mergeTemplates() method.

The logic should be the same for both module methods. Tests should be added whether the order makes a difference with the objects that have roles with templates, and templates with roles.
