Summary

Currently, we use the full transaction size for a minimum fee calculation.
This commit changes the behavior to charge for the additional (minimum) of
179 bytes it would take to spend any newly created outputs.

Test Plan
make check && ./test/functional/test_runner.py --extended

The previous GetTxSize() cached the size internally to the mempool entry. This does not. I am curious as to if I should make the mempool entry cache this data.
