cfbc3f73ec Pyhton: add test for conflicting summaries 
We noticed that when
- a function has more than one summary (with different charpred)
- one summary is subsumed by a subpath (or something happens around the function being extracted)
- the function is called multiple times(we needed at least three)
one of the summaries would no longer lead to flow.

7a3ee0f5f8 Python: Make IterableSequenceNode LocalSourceNode 
We do this to remove the inconsistencies, and to be ready for a future
where type-tracking support content tracker of depth > 1.

It works because targets of loadSteps needs to be LocalSourceNodes

predicate loadStep(Node nodeFrom, LocalSourceNode nodeTo, Content content) {

cdf4dd16f0 Python: Fix module level flow for iterable unpacking 
(and for * patterns in match)

Since `PhaseDependentFlow` uses the following predicate, that relies on
.getScope() to be present for there to be any importTimeFlow (flow at
toplevel scope), it's important that data-flow nodes implement `.getScope`.

```
private predicate isTopLevel(Node node) { node.getScope() instanceof Module }
```

By implementing getScope, we can now rely on default implementation of
`getEnclosingCallable` in DataFlow::Node:

```
  /** Gets the enclosing callable of this node. */
  DataFlowCallable getEnclosingCallable() { result = getCallableScope(this.getScope()) }
```
