its not really shown, but perhaps her ORIGINAL plan was to kill everyone else in the room too, or to make a scene at the conference
Rarely does a superhero movie take the time to ensure that the moments of conflict come at the most logical (and character-driven) time. If Mystique really wanted to kill Trask, she could have very easily done so at any time with almost zero risk. Why go through all those hoops? Cause the movie needs action scenes with (created) character conflicts.
Same is true for any of these movies -- why attack Steve Rogers in an elevator when a SHIELD agent could just inject something like nerve gas into Cap's elevator and kill him (or some other such easy device). Because the movie needs action scenes. It's a fundamental flaw of the genre, perhaps.

More spoilers!!!!!
I would say that for the purpose of this specific discussion, there's no evidence to suggest that Mystique INTENDED to kill Trask during this specific meeting. Perhaps she was in more of an espionage role trying to learn about plans, weapons, and other potential collaborators. But she was revealed, and flustered and decided to act. I don't think this is too unreasonable, ALTHOUGH I agree its a bit convenient. But I do feel like they thought about it at least a little bit.
I find it harder to believe that they didn't use Quicksilver more.
I don't think they could have used Quicksilver more. He could have ended almost all of the conflicts that followed with very little fuss.
