Application locked when editing item

[matejm]

If application is locked when item is being edited, item is currently saved. But after unlock, editItemDialog should be opened again with same item.

Currently app cannot be manually locked if any dialog is opened. Only scenario when this could happen is when app is automatically locked.

I think there is a important question answer before diving into this issue: Enpass only renders lock screen content over all the ui and doesn't even clean the ui.

My first thought was that one could exploit ui vulnerabilities and get information out of it. But in fact, to do that one has to access app's RAM and read the variables out of it - and if he is able to do that, then celeaning the ui won't help - the intruder only has to wait for unlock which will deffinetly happen if user is in the middle of editing an item.

@matejm @DzinVision your thoughts?
