0x from ETH Private key - Good to remove

[eosauthority]

This is an enhancement and will help a few users

1. User enters ETH Private key 0x68751f873da1063ed9afaee4785102f063dee014bcdcb88fcc135a76d8875860 (this is random ETH Private key, safe public
2. There is a 0x prefix, this works however with the prefix to show ETH Public key (conversion)
3. Change dropdown to EOS, the keys don't convert and there is no warning to the user.

Might be easier to trim out 0x if it is present on Step 3? It is hopefully a quick fix until I missed something entirely. We had a user struggle with this and we found this was the cause!
