Tests were failing when running coverage because none of the addresses
in the testrpc run by the coverage had any tokens allocated to them.
This is because the config file uses addresses derived from a specific
mnemonic, and the coverage testrpc was using a random one each time.
Specify a mnemonic to make sure coverage generates the same addresses
as those specified in the config file
