color.uda.priority.L being taken over higher precedence active even when rule.precedence.color is set

#### To report a bug...

* What command(s) did you run?
With this configuration:
```
include /usr/share/taskwarrior/no-color.theme

rule.precedence.color=uda.,deleted,completed,active,keyword.,tag.,project.,overdue,scheduled,due.today,due,blocked,blocking,recurring,tagged

urgency.user.tag.blocking.coefficient=6

color.active=rgb410
color.tag.PR=rgb035
color.uda.priority.H=rgb542
color.uda.priority.L=gray6
```
and these task:
```
ID Active Age P Tags Description Urg
11 1min 1min L test Test-Active 6.6
12 1min L test Test-Low 2.6
10 1min test Test-M 0.8
```

* What did you expect to happen?

I expect Test-Active to be orange (color.active) as active is later in the priority list. (This also happens if uda. is at the end of the list).

* What actually happened?

However it is gray (color.uda.priority.L).

The order of the rules does not seem to matter.


* Paste the output of the ```task diag``` command.
