Fixes https://github.com/llvm/llvm-project/issues/58774

When merging to Access objects, don't call reset() on the content, but it needs
to be set to nullptr instead. The latter means that the content was determined
to be unknown. Added an assertion to getWrittenValue() to which would have
caught this more quickly.
