Tag Editor plugin corrupts tag keys and values

[Aleksandr Dezhin]

The situation can be reproduced as follows:

1) Create empty osm layer with 2 nodes. For first node add tag key=v, for second key1=v.

2) Go to tag editor for first node

3) Use mouse or Tab key to active cell containing "v". Once the cell is activated, the value will change to "vending" or something other from presets. (case 1)

4) Add new line using add button or Tab key, and activate cell containing "key". Once the cell is activated, the value will change to "key1". (case 2)

It is not always such a behavior plug-in can be seen on time, and quite often it leads to data corruption ...
