Affects Artifact Deployer plugin version 0.33

Test steps:

• Configure a job that deploys some artifacts to /prefix/path1
• Build a one or two builds of this job
• Change its configuration to deploy to /prefix/path2

Expected result:
All builds should have working links for artifact download (by either moving existing artifacts to new location, or keeping old links to previously built ones)

Actual result:
Older builds have broken download links referencing /prefix/path2, which is only populated by newer builds.
