Embind: call decrementExceptionRefcount upon catching

The note at
<https://emscripten.org/docs/porting/exceptions.html#handling-c-exceptions-from-javascript>
is a bit vague whether decrementExceptionRefcount would only be needed for
Wasm-based (-fwasm-exceptions) exceptions, or also for the JS-based
(-fexceptions) ones that we currently use.  (But it does state clearly that for
the latter we need to manually call incrementExceptionRefcount first.)
