JiraImportFileServiceImpl provides functionality to modify the JIRA import file. The JIRA URL replacement logic was originally extracted from com.atlassian.studio.importer.impl.LegacyStudioImportManager (former name com.atlassian.studio.importer.StudioImportManager), the user renaming logic was added in AOD-2656. In order to isolate it, only com.atlassian.jira.config.properties.ApplicationProperties and com.atlassian.studio.common.StudioInfo have to be mocked. The unit contains also the ZIP extraction functionality contained in com.atlassian.studio.importer.impl.util.ZipFileInputStream, thus the test should incorporate the tests originally contained in the removed com.atlassian.studio.importer.TestImportZipExtractorImpl (r106231).
