Many FC_ASSERTs & FC_THROW_EXCEPTIONs have incorrent format str or empty str, prevent display more message.

[btsabc]

eg:

bitshares-core/libraries/db/include/graphene/db/index.hpp

Line 111 in dc7eb35

FC_ASSERT( maybe_found != nullptr, "Unable to find Object", ("id",id) );

get_call_orders "1.3.0" 1
ouput:
Assert Exception: maybe_found != nullptr: Unable to find Object

if code change to：
FC_ASSERT( maybe_found != nullptr, "Unable to find Object ${id}", ("id",id) );
will show id msg,more helpful.
