Unable to update plane booking length

[wiggydave10]

1) Use a PPL user

2) Book a 1 hour Aeroplane

3) Modify and change to 2 hour

See: "You already have a booking at this time" error.

Expect: My existing booking to update to 2 hours rather than an hour.

Note: Also applied if you have 2 hour aeroplane and move it back an hour (e.g. 10am for 2 hours, modify to 9am for 2 hours) see same error.
