Description

When an external definition such as:
  ../gamma/delta delta-ext
configures a file external, a switch to a different branch won't update the
external's def_repos_relpath in the EXTERNALS table.

If a working copy in such a state is upgraded (even for no-op upgrades from the
same version of svn to the same version of svn), the node kind of this external
in the EXTERNALS table switches from 'file' to 'unknown'.

The working copy can then no longer be updated. Every attempt to update the
working copy errors out as follows:

svn: warning: W195017: The file external from '[...]/branch/gamma/delta' cannot
overwrite the existing versioned item at '[...]/wc/epsilon/delta-ext'

At revision 3.
subversion/svn/update-cmd.c:175: (apr_err=SVN_ERR_CL_ERROR_PROCESSING_EXTERNALS)
svn: E205011: Failure occurred processing one or more externals definitions
