Remove obsolete uses of obsolete functions

* src/minibuf.c (minibuf_conform_representation): Remove.
(Ftry_completion): Don't call it.
(Ftest_completion): Don't use the obsolete Fstring_make_unibyte or
Fstring_make_multibyte; they don't serve any useful purpose here.
We don't try to equate unibyte and multibyte raw bytes in symbol
lookups elsewhere and there is no reason to do it here.
