merge: rework iteration over mergeresult object in checkpathconflicts()

Instead of following pattern:

```
for f, (m, args, msg) in mresult.actions.items():

    if m == mergestatemod.ACTION_*:
        ...
    elif m == mergestatemod.ACTION_*:
        ...
    ....

```

We do:

```
for (f, args, msg) in mresult.getaction((mergestatemod.ACTION_*,)):
    ...

for (f, args, msg) in mresult.getaction((mergestatemod.ACTION_*,)):
    ...
....
```

This makes code bit easier to understand and prevent iterating over actions
which we don't need.
