[FIXED JENKINS-16776] surefire-reports not detected for android-maven-plugin

(Or should we just check the status code?)

translation cleanup

purged duplicated translations for GlobalCrumbIssuerConfiguration
("Prevent Cross Site Request Forgery exploits").
Changed property name "Crumb" to "Crumbs" because this is the value that the existing translations actually use.

Improve UpdateSiteTest by adding valid Update sites

Removing old static field, which was not friendly to tests, especially multithreaded runners.
Cleaned up existing tests to use updateDirectly rather than POSTing raw JSON.

[JENKINS-15156] AbstractProject.builds accessed by Maven & matrix module builds before onLoad or onCreatedFromScratch called.
Seem to need to keep the deprecated no-arg RunMap initializer though it is unclear to me how it could work.

so iterate on itemGroup.getItems and filter by job names

used to browse workspace and run scm polling

Seems that the RunMap must be initialized before updateTransientActions, which uses it, is called.

[FIXED JENKINS-15156] Initialize AbstractLazyLoadRunMap.dir for newly created jobs.
