extensions: raise when trying to find an extension that failed to load

extensions that depend on other extensions (such as record) use this pattern
to check if the dependant extension is available:

    try:
        mq = extensions.find('mq')
    except KeyError:
        return

but since if an error occurs while loading an extension it leaves its entry
in the _extensions map as None, we want to raise in that situation too.

(rather than adding another check if the return value is None)

Create configuration

  $ echo "[ui]" >> $HGRCPATH
  $ echo "interactive=true" >> $HGRCPATH

help record (no record)

  $ hg help record
  record extension - commands to interactively select changes for commit/qrefresh
  
  use "hg help extensions" for information on enabling extensions

help qrecord (no record)

  $ hg help qrecord
  'qrecord' is provided by the following extension:
  
      record  commands to interactively select changes for commit/qrefresh
  
  use "hg help extensions" for information on enabling extensions

  $ echo "[extensions]"     >> $HGRCPATH
  $ echo "record="          >> $HGRCPATH

help record (record)

  $ hg help record
  hg record [OPTION]... [FILE]...
  
  interactively select changes to commit
  
      If a list of files is omitted, all changes reported by "hg status" will be
      candidates for recording.
  
      See "hg help dates" for a list of formats valid for -d/--date.
  
      You will be prompted for whether to record changes to each modified file,
      and for files with multiple changes, for each change to use. For each
      query, the following responses are possible:
  
        y - record this change
        n - skip this change
  
        s - skip remaining changes to this file
        f - record remaining changes to this file
  
        d - done, skip remaining changes and files
        a - record all changes to all remaining files
        q - quit, recording no changes
  
        ? - display help
  
      This command is not available when committing a merge.
  
  options:
  
   -A --addremove            mark new/missing files as added/removed before
                             committing

   -d --date DATE            record the specified date as commit date
   -u --user USER            record the specified user as committer
