Upgrade overwrites file entry_points.txt

[JaegerFrank]

The Upgrade with

sudo pip install --upgrade --no-deps MapProxy

overwrites the file /usr/local/lib/python2.7/dist-packages/MapProxy-1.15.1.dist-info/entry_points.txt

The content of the correct working file is

[console_scripts]
mapproxy-seed = mapproxy.seed.script:main
mapproxy-util = mapproxy.script.util:main

[paste.app_factory]
app = mapproxy.wsgiapp:app_factory
multiapp = mapproxy.multiapp:app_factory

[paste.filter_factory]
lighttpd_root_fix = mapproxy.util.wsgi:lighttpd_root_fix_filter_factory

[paste.paster_create_template]
mapproxy_conf = mapproxy.config_template:PasterConfigurationTemplate

The replacement contains only the first 3 lines. (Section 'console_scripts')
Result is an "Internal Error" when browsing the MapProxy-URL.

I have to copy the file (from old path) before the upgrade an replace the new file with the old version after upgrade.
The old version-path is deleted on upgrade, so after "pip install --upgrade" the correct file is not available for replacement.
