Task sync error with DAVdroid 1.2.2

[bugreporter]

Since DAVdroid 1.2.2 the setup of task synchronization fails with OpenTasks installed on Android 5.1.

Steps to reproduce:

• Clear device (in my case Fairphone 2 with Open OS 16.06)
• Install OpenTasks
• Install DAVdroid 1.2.2
• Setup account (in my case posteo.de)

Observed behavior:

• Task list does not appear in OpenTasks
• DAVdroid shows 'tasks sync. interval' to be 'not available'

Expected behavior:

• Task list should appear in OpenTasks

Workaround:

• Use DAVdroid 1.2

Thanks for the report. This has been fixed with eb70f8690f1b04a1104d3729843ddcf881fa8ee0 and should be working again in DAVdroid 1.2.3.
