[FIX] Integrate: Fix call to new deferred commit

[stuart-cls]

While working on #634 I found a call to commit that got missed in #622

I wasn't sure which call ("now" or "deferred") was appropriate, I chose "now"

I changed to "deferred". So the current "standard" is to use deferred anywhere except for the new data received or explicit commit button clicks.
