Fix broken roave/bc-check test

[acrobat]

Previously the bc-check was broken due to a changed tag format, which causes an incorrect version/tag to be guessed. This was fixed in 5.0

Detected last minor version: 2.14.0

In Process.php line 256:

  The command "'git' 'rev-parse' '2.14.0'" failed.

  Exit Code: 128(Invalid exit argument)


  Output:
  ================
  2.14.0


  Error Output:
  ================
  fatal: ambiguous argument '2.14.0': unknown revision or path not in the working tree.
  Use '--' to separate paths from revisions, like this:

I think this is breaking because the last release had a v on the front by mistake?

[acrobat]

No not by mistake, I switched to a cli tool to do the merges/releases etc and this tool tags versions with the v prefix. which actually doesn't matter for composer, but the version lib used in roave lost that prefix along the way so an incorrect tag was searched. This was fixed in roave/backward-compatibility-check v5.

Ah, right. 👍
