```
just the sanity check added in 6ac3f84095
The following exceptions should be expected:
FileNotFoundError: given wallet path does not exist
StorageReadWriteError: given file is not readable/writable or containing folder is not writable
InvalidPassword: wallet requires a password but no password or an invalid password was given
WalletFileException: any internal wallet data issue. specific subclasses can be caught separately:
- WalletRequiresSplit: wallet needs splitting (split_data passed in Exception)
- WalletRequiresUpgrade: wallet needs upgrade, and no upgrade=True was passed to load_wallet
- WalletUnfinished: wallet file contains an action and needs additional information to finalize. (WalletDB passed in exception)
Removed qml/qewalletdb.py
This patch also fixes load_wallet calls in electrum/scripts and adds a qml workaround for dialogs opening and closing so
fast that the dialog opened==true property change is missed (which we need to manage the dialog/page stack)
The few other cases that used SimpleConfig.get_instance() now
either get passed a config instance, or they try to get a reference
to something else that has a reference to a config.
