Incorrect stakers' authorization amount shown #11
Description
Currently the TACo app authorization shown on tacoscan is obteined through mainnet-staking-subgraph, that get the authorization amounts from the staking contract.
Due to changes on threshold-network/solidity-contracts#171, this amount is not correctly calculated by the subgraph: the authorization amount shown for beta stakers is 0 if you ask the staking contract. For example, for this beta staker:
https://tacoscan.com/?staker=0x331f6346c4c1bdb4ef7467056c66250f0eb8a44f
Total authorized is 0 in tacoscan. But this is not true.
A new subgraph listening for authorization events on TACoApplication contract would work better.
Another option could be calling the function authorizedStake(address) on TACoApplication contract or TACoChildApplication (the latter updates faster).
