Adjust coingecko prices based on token decimals (#2899)

# Description
Fixes: #2887

# Changes
Adjust returned native token prices when the quoted token has a
different amount of decimals than the native token to be inline with all
other native price estimator implementations.

Additionally I also removed the option to quote without denominating in
any token mainly to reduce complexity.

## How to test
Added an `ignored` unit test that checks that prices make sense.
Also compared prices returned for `wxdai` and `usdc` with prices logged
in our infra.
