Test: Too high of tolerance

[ericpassmore]

Transferred from AntelopeIO/reference-contracts#94 original author heifner

Many tests have too high of a tolerance:
https://github.com/AntelopeIO/reference-contracts/blob/cd645b54a176f0c8b5f2f5ea9b21f47b7f9bf7eb/tests/eosio.system_tests.cpp#L1013
I'm assuming the test author meant 1e-5 not 1e+5.
All the tests that use a tolerance should be inspected and fixed.
