Improve Error Messaging when Deposit transactions are reverted/or fail

[ramaruro]

When initiating a Deposit, in Step 2, when the initial transaction (fee payment?) fails in Metamask the ensuing error is very unclear for an end user. It looks like it is reading straight from Ethereum, but very few people would know what to do with that.

Suggestion: capture the reason of the error (e.g. System at Minting Capacity) and display that. Also explicit that no fee was spent, only Gas (?).

Below is the message and the screenshots.
