File modified during upload should not be handled by the local ignore list

[TheOneRing]

If an upload of a file fails 3 times in a row because it was modified during sync, we add it to an ignore list.

This can easily happen for files managed by an IDE.

@Talank I think there was a related squish test?

[Talank]

We only had one test for blacklisted file, which is skipped currently

client/test/gui/tst_syncing/test.feature

Line 248 in 2f5547e

Scenario: Filenames that are rejected by the server are reported

I do not think there is a test for this like try to sync upto 3 time ...
