fix version 1.7 removed in Jira

[Sebastian Nagel]

Hi,

please take care not to remove the fix version
when applying bulk changes, e.g., 2.2 => 2.3
Alternative fix versions (1.7) are not kept.

Luckily Jira is quite powerful, I restored the 1.x
fix version using this awful filter:
  project = NUTCH AND fixVersion in ("2.3")
  AND status = Open AND updated >= 2013-05-21
  AND affectedVersion in ("0.8", "0.9", "0.9.0", "1.0", "1.1", "1.2",
"1.3", "1.4", "1.6", "1.7")
  ORDER BY issuetype ASC, priority DESC

Cheers,
Sebastian
