refactor: test: Return std::span from StringBytes

Browse source 
This is possible and safe, because std::span can implicitly convert into
Span, if needed.

Changing this function is required, because std::span requires the
extent template parameter to be specified as well.

Instead of explicilty specifying them, just let the compiler derive the
template parameters correctly.

Otherwise, there would be a compile error later on:

 src/wallet/test/db_tests.cpp:39:37: error: no matching function for call to ‘as_bytes<const char>(<brace-enclosed initializer list>)’
