Context is not respected by `modify` command.

* What command(s) did you run?

```
## Here's the exact set of commands I ran on an empty task warrior instance running 3.2.0 to simulate the issue.
task add main1
task add main2
task context define personal "project:Personal"
task context define work "project:Work"
task context personal
task add p1
task add p2
task context work
task add w1
task add w2
task status:pending modify +testtag
task context none
task list
```

```
## Here's the actual output
$ task list

ID Age Project Tags Description Urg
1 53s testtag main1 0.8
2 52s testtag main2 0.8
3 43s Personal testtag p1 1.8
4 42s Personal testtag p2 1.8
5 40s Work testtag w1 1.8
6 39s Work testtag w2 1.8

* What did you expect to happen? What actually happened?
Modify should respect the context that is set and only update the appropriate items. However, it updates everything. Note that `task list` works as expected.
* Paste the output of the ```task diag``` command.
```
$ task diag
