Fix SI-5853.
This solves two issues.
First, up to now the newly generated symbols for normalized
members were not being added to the declaration list of the
owner during `specialize`. Now they are.
Second, during `extmethods`, the extension methods generated
get an additional curried parameter list for `$this`.
Trouble was, after that, during `uncurry` and before `specialize`,
these curried parameter lists were merged into one list.
Specialization afterwards treats extension methods just
like normal methods and generates new symbols without the
curried parameter list.
The `extensionMethod` now takes this into account by checking
if the first parameter of a potential extension method has
the name `$this`.
