Fix gRPC for mint annual-provisions

[amaury1093]

Description

This PR fixes the error on CLI command q mint annual-provisions. It may affect other commands that deal with sdk.Dec.

It is related to cosmos/cosmos-sdk#8392.

To Test:

Run a gaiad node (doesn't need to be with the hub genesis, an dummy genesis works too).

Then run the q mint annual-provisions CLI command.

Before

./build/gaiad q mint annual-provisions           
Error: panic message redacted to hide potentially sensitive system info: panic
--snip--

After

./build/gaiad q mint annual-provisions

Yeah, I ran some other commands on the CLI, with my test genesis file, it works. I did not try on the hub though (might take some time on my side).

I suspect this is because of Amaury's membership. See the PR that works for this cherry-picked commit #650. I'm going to merge in and we can add Amaury to a team.
