Bug #1323633 has bitten me a few times on date, I always run `./mach taskgraph full ...` since the verification steps have been added.

And in this case, a treeherder duplicate symbol, I don't see why only validating with a target set is ideal/wanted, when the same push can have multiple target sets run on it. -- We should just validate with the whole graph.

Hammad, FYI -- let's do these checks earlier in the task-graph generation process so we catch errors sooner.
When transitive closure for full task graph is computed some more dependent tasks are added so I thought maybe I should do the check after obtaining a target task graph.

My understanding:

* FULL
  - set of all tasks that can possibly run (scheduled by taskcluster) on this push
  - computed first
* TARGET
   - Tasks that should run on this push
   - First by selecting all tasks that would match the 'target' conditions
   - Then by adding in tasks that are dependancies of those selected ones
* OPTIMIZED
   - Tasks that *will* run on this push
   - ...
So basically all possible tasks are loaded resulting in full task graph,
then we identify target tasks and determine there dependencies resulting in target task graph.
Right -- so if there are duplicates in target or optimized, then those duplicates will also exist in the full graph.
ahh right, checking after generating full task graph will catch errors early :)
