Fix elements interchange

[Gabriel Stanovsky]

Predicates are sometimes wrongly interchanged.

FEMA Urges East Coast Residents to Prepare for Hurricane Sandy
FEMA Urges East Coast to aim for Hurricane Sandy

The output from PropSWrapper doesn't introduce this error.
@kleinay, can you please check what's your output for this sentence?

{'Entities': {'A1': ('Prepare', (6,)),
              'A2': ('Hurricane Sandy', (8, 9)),

Also seems to happen with entities:

Hurricane Sandy Bears Down on East Coast
Hurricane Sandy Bears States
[States is coreferred to "Down"]

[Ayal Klein]

Is this error still relevant? I don't know what to check at the json, is it supposed to be a coreference error?

[Ayal Klein]

This was fixed. Caused because the lemma of some words was empty (SpaCy couldn't lemmatize it), and therefore was marked as coreferring (same lemma).
