This fixes a bug where the position of a task would not be calculated correctly when the task was moved next to another recently moved task. The problem was caused by the calculation of the new position referring to the old value of the position attribute, because it was not updated in the local store.

This somehow weirdly fixes the test. I have no clue why. Regardless it should be better than before, because a button (DropdownItem) should never contain another interactive element (the setBucketLimit input and save button).
The test failed because I replaced a v-if with v-show. I do not know _why_ this made the test fail. When I reproduced the test step by step it worked for me…
BREAKING CHANGE: The bucket id of the task model is now only used internally and will not trigger a change in buckets when updating the task.
This resolves a problem where the task update routine needs to know the view context it is in. Because that's not really what it should be used for, the extra endpoint takes all required parameters and handles the complexity of actually updating the bucket.
This fixes a bug where it was impossible to move a task around between buckets of a saved filter view. In that case, the view of the bucket and the project the task was in would be different, hence the update failed.
