config overwritten on user/project modules save

When a user modifies and saves the init.lua or a project module file the
reload_customizations() function was performing unnecessary reloading
of core.config and core.style. This resulted on the replacement of config
tables with new tables, breaking all active references been used by
the consumers of this config options. Been redundant this means
that every consumer was using its own copy of a configuration table
different from the one referenced on core.config and user changes not
taking place.
