915e34112b5a4c2ef391d7e3706603bcd6f62a2a qt: fix issue when disabling the auto-enabled blank wallet checkbox (Jarol Rodriguez)
Pull request description:
As detailed by #151, On `master` a user can create the confusing scenario where you have a disabled `Encrypt Wallet` checkbox and a selected `Disable Private Keys` checkbox after unselecting the auto-enabled `Blank Wallet` checkbox.
This commit makes it so that when the `Blank Wallet` checkbox is auto-selected after the user selects `Disable Private keys`, unselecting it will also unselect the `Disable Private Keys` checkbox, which in turn re-enables the `Encrypt Wallet` checkbox.
Below are screenshots comparing the behavior of selecting `Disable Private Keys` then unselecting the `Blank Wallet` between `master` and this `PR`:
**Master:**
| Select `Disable Private Keys` | Unselect `Blank Wallet` |
| ----------------------------- | ------------------------ |
|  |  |
**PR:**
| Select `Disable Private Keys` | Unselect `Blank Wallet` |
| ----------------------------- | ------------------------ |
