BIP44 soft wallet falling back to rolling backups

[gary-rowe]

Made a BIP44 soft wallet (Mycelium compatible) and have seen this occur after a full synch, exit, unlock sequence:

KeyChainGroup#fromProtobufEncrypted There are 603 keys.
[2015-02-24 22:02:11,202] ERROR [safe-fixed-unlock-wallet-0] o.m.h.c.m.WalletManager - WalletManager error: java.lang.IllegalArgumentException No key found for absolute path M/44H/0H/1/1. ! java.lang.IllegalArgumentException: No key found for absolute path M/44H/0H/1/1.

The report screen correctly shows a fallback to a rolling backup and the wallet syncs back into position but it is annoying.

This is identical to #368 which has been deferred to Release 0.1. Closing as duplicate.
