Since `ember-moment@10.0` it's not been necessary to use the `ember-cli-moment-shim` package, with `moment` instead being usable directly via `ember-auto-import`. Getting rid of the shim package is necessary for compatibility with `embroider`, Ember's new build tooling.
- dropped `ember-cli-moment-shim` dependency
- added `moment-timezone` dependency and updated all imports to reflect the different package
- worked around `ember-power-calendar` having `ember-cli-moment-shim` as a sub-dependency
- added empty in-repo-addon `ember-power-calendar-moment` to avoid `ember-power-calendar` complaining about a missing package
- added `ember-power-calendar-utils` in-repo-addon that is a copy of `ember-power-calendar-moment` but without the build-time renaming of the tree for better compatibility with embroider

- adds tests to cover more mrr event scenarios

MRR start date value for charts was being calculated with start value as 0, assuming we have the data for first date in our range to use as start value. Since the events data returned only has data on dates where any MRR event happened, in case the first date in our range didn't have any. data we started from 0 instead of value on previous date. This fix
- updates calculation to pick the start value for chart based on value on last date in our range(30 days)
- adds unit tests for stats
