A terminal in a symbol's definition saved without its orientation
attribute crashed QElectroTech whenever the project was opened, in the
GUI and with --resave alike: Qet::orientationFromString() read the
first character of an empty string. Hand-edited or generated symbols,
or a damaged file, can hold such a terminal.
An empty string is now an inconsistency like any other, and the terminal
faces north, as the function's comment already said. Every non-empty
string gives the same orientation as before.
tst_terminalnoorientation runs the real binary's --resave on
fixtures/terminal_no_orientation.qet (unlinked_contact_label.qet with one
terminal's orientation removed): it crashes without the fix.
