Subject: Fix default gas limit for fake txs in TraceCollectionSubprovider

This hex string is required to be prefixed with '0x'. If it does not have that
prefix, then the call to unmarshalTxData below will fail with:

	BigNumber Error: new BigNumber() not a number: 5b8d80

This default value is overridden if the incoming call already has a gas
estimate, in which case the parse error above does not happen. This is probably
why the error wasn't previously noticed.
