Bug 1022115 - [Contacts] Can't see detail of contact when multi import via Bluetooth

Can we extract this `if` condition to a function wich we could pass parameters?

Something like:
`if (ActivityHandler.allowActivity(['list of disallowed','activity','names'])`

And check inside if `currentlyHandling` and as well the names passed are not bieng handled? We could reuse the code in several places.

With no parameters could be just like checking `ActivityHandler.currentlyHandling`

wdyt?
