fix: remove forced settings for shadercache (#95)

Fixes regression from 0b49ae9. ShaderCache settings would always be
default.

Removing redundant load settings exposed where we were setting default
settings for ShaderCache. This is unnecessary due to default values and
the fact we ship a config file that is fully populated.
