merging phases of the same name on the build page

[Inetov]

phases with the same name merge into one on the build page. on the page of the job itself, this is displayed correctly.

screenshots:

• page of build. different phase names (displayed correctly):

• page of the job itself. phases with the same name (displayed correctly):

• page of build. phases with the same name (error! phases merge!):

please fix this as soon as possible, it affects my work.
