Backwards Compatible Calls cause exception

[nduitz]

Using pow_postgres_store the first time logging in after application startup causes an exception:

function Pow.Postgres.Store.keys/1 is undefined or private

The issue here seems to be:
defp has_binary_keys?(store) do: not function_exported?(store, :all, 2)

Documentation states:

Note that this function does not load the module in case it is not loaded.
Check Code.ensure_loaded/1 for more information.

So simply calling Code.ensure_loaded(store) upfront fixes the issue.

To reproduce this behaviour setup pow_postgres_store as store and try a login directly after application startup.

Thanks! 🙏

The PR looks good though I try to get around all Code.ensure_compiled?/1 and Code.ensure_loaded?/1 calls due to #329. Guess Pow 1.1.0 can't come soon enough now! I want to review a few alternative ideas but otherwise get this merged.

Out of curiosity, does this only occur if you start up with mix phx.server instead of running a release?

I can confirm that this does only occur running mix phx.server.

But thanks for merging this <3
