Describe the issue you encountered:
Advance setting button is clickable when wallet is being created which makes no point until the wallet is actually created

Expected behavior:
Advance settings button should be disabled till Brave wallet is created

• Platform (Win7, 8, 10? macOS? Linux distro?):
  All
• Brave Version:
  0.12.6 Preview 1
• Steps to reproduce:
  1. Do a new install of the preview build
  2. Enable payments, Advance settings button is shown which can be clicked
  3. After wallet is created, delete all ledger.* files from session folder, advance button is still clickable which makes no sense.

@mrose17 for triage but I just didn't want it in 0.12.6 so remove that.

@bbondy - thanks for the heads-up

@srirambv - it's kind of hard for me to think this is a problem. if someone starts deleting files underneath the browser, then i think that we can't really view that as something to guard against.

however, i'll add some bullet-proofing...
