    manifest_get_default_revision must deal with / in branch names

    When the manifest default revision is 'r/stx.6.0',
    manifest_get_default_revision was returning 'r'.
    A sed clause intended to catch '/>' was grabbing the wrong
    '/' character.

    Split the sed expression into two seperate expressions.

    Tested with:
       <default revision="r/stx.6.0" remote="stx-staging"/>
       <default revision="stx.6.0" remote="stx-staging"/>
       <default revision="r/stx.6.0"/>
       <default revision="stx.6.0"/>
