If I resize active logical volume using blivet, it leaves the volume deactivated.

I can see in blivet log:

    INFO:blivet: executing action: [0] Resize Device (Grow) lvmlv test-1 (id 7)

Version-Release number of selected component (if applicable):
python-blivet-0.13-1.fc20.noarch

How reproducible:
always

Steps to Reproduce:
Use this script ('b' is Blivet instance, 'blivet' is the blivet module):

lv = b.lvs[0]
action = blivet.deviceaction.ActionResizeDevice(lv, 60)
b.devicetree.registerAction(action)
b.devicetree.processActions(dryRun=False)
