Replace GetProjectAllocatedBandwidth by GetProjectBandwidth which calculates
used bandwidth from allocated and settled bandwidth recorded in the
project_bandwidth_daily_rollups table.
For each day in the month, if the allocated bandwidth is expired, it uses the
settled bandwidth for computing used bandwidth.

I also fixed a minor UTC issue with this test as well.
