Cannot set Lido withdrawal credentials using the UI

[skozin]

Nothing happens when one tries to update DAO withdrawal credentials using the client UI.

Steps

1. Open DAO client interface, make sure DAO holder account is active.
2. Go to Lido app.
3. Press Edit button on Withdrawal Credentials line.
4. Enter 00f45d8e2c47371928bfeca7a52b7e0b67f4c0aa0f10d3ecebf7381158acf4cd in the field.
5. Press "Set withdrawal credentials".

Expected result

The app offers to start the voting process.

Actual result

Nothing happens.

Notes

Nothing happens if one selects an account that holds no DAO (LDO) tokens, too.

It started working for some reason. @azat-s, feel free to close this if you fail to reproduce.

@skozin
It seems the method only accepts hexadecimal strings prefixed with '0x'.
As per issue #149, I will add some validation rules. E.g. the string must be prefixed with '0x' and must be of length n, which is how many exactly (not counting the prefix)?

Alternatively, I can add the prefix the string myself, if none is present.

The withdrawal credentials is a 32-byte number, so the string must contain 64 characters excluding the 0x prefix.

Yep, that would be perfect!
