#615 Map empty for a while after "no solution" to routing

[Jyrki Kuoppala]

On micremulator:

1) go to sea
2) search & route to (from virtual keyboard or via "c" from real keyboard, doesn't seem to matter)
3) GpsMid empties the display and shows "no Solution found", after which map remains empty
4) map is returned to maybe after 10-15 seconds

( Solution being capitalized is also a bug )
