Do not generate useless methods inside wrapper for inline class

Fix for test data (inlineFunctionInsideInlineClassesBox.kt) is needed
 to avoid check about "no inline functions".

 This check has two steps: first, names of inline functions from
 the metadata are loaded, then these names are checked that they are
 presented for physical methods in the classfile.

 Because now there are no physical methods in the classfile, we can't pass
 the second check, therefore this fix is needed.
