restore sugar-launch by bundle id substring, fixes #897

sugar-launch uses GetBundlePath which calls bundleregistry.get_bundle().

In this patch, the get_bundle() method is changed to retain as much of
the original API as possible, yet in the situation where it might return
None it will now return a bundle if there is only one bundle that
matches the search string.

Patch tested on Sugar 0.84.10 on OLPC XO-1.5 build os108.

Test case:

import jarabe.model.bundleregistry
registry = jarabe.model.bundleregistry.BundleRegistry()
tests = ['org.laptop.Terminal', 'Terminal', 'terminal', 'e', 'asdqweas']
for x in tests:
    y = registry.get_bundle(x)
    if y is None:
        z = 'None'
    else:
        z = y.get_bundle_id()
    print x, z

Output before patch:

org.laptop.Terminal org.laptop.Terminal
Terminal None
terminal None
e None
asdqweas None

Output after patch:

org.laptop.Terminal org.laptop.Terminal
Terminal org.laptop.Terminal
terminal org.laptop.Terminal
e None
asdqweas None
