MetaMorpho total shares is incorrect

[AustinWoetzel]

The metaMorphos query returns totalShares per the following query
query getMetaMorphos { metaMorphos { totalShares } }

however this number does not reflect the actual state of the contract when you query 'totalSupply'. Total Supply on the contract is a number higher than the subgraph number.

We believe this to be caused by shares minted to the fee collector not being captured in the events that increment shares in the subgraph. When we query the shares balance of the fee collector, it perfectly adds to the subgraph totalShares to equal the total Supply on the contract.

Solution: total shares in the subgraph needs to be incremented any time that shares are minted to the fee collector.
