fetchLatestIndex in SnapPuller just logs exceptions

[Mark Miller]

Any particular reason that SnapPuller just logs exceptions in boolean 
fetchLatestIndex(SolrCore core) throws IOException ?

Here and there it might throw one, but generally it just logs and allows 
the code to continue - often you are just going to hit a nullpointer a 
line or two down. Should we be throwing IOException or something rather 
than logging and continuing?
