Method "annotate_exception", may fail when data value is binary

[brunsgaard]

From client.py we have:

2528     def annotate_exception(self, exception, number, command):
2529         cmd = unicode(' ').join(imap(unicode, command))
2530         msg = unicode('Command # %d (%s) of pipeline caused error: %s') % (
2531             number, cmd, unicode(exception.args[0]))
2532         exception.args = (msg,) + exception.args[1:]

the imap'ing at line 2529 may throw an UnicodeDecodeError when command holds binary data.

The following is the ouput of print(command) before line 2529,

('ZADD', 'test.sms.normal:delayed', 915148800, '\x08\xe3\xb6\x12\x12\x1b\xc3\x85ello World, %1, --MYTAG--\x1aZ\x08\x01\x10\x82\x04\x18\xf1\xf7\' \xae\x02(\xd0\x052?\t\xaeG\xe1z\x14\xae\xf3?\x12\x03CAD\x1a\x03P01"\x13Example charged SMS*\x04SC122\x0fExample service:\x03foo:\x03bar"\x0f123456789012345(\x80\xa0\xb0\xb4\x032\t--MYTAG--2\x02%1:\x041234@\x01H\x80\xa3\x05P\x00X\x02b\x06\x05\x04\x0b\x84#\xf0j\x17payload encoded as b64\np\x01x\xe2\xb6\x12\x82\x01\x01A')

and it throws the follwoing exception

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe3 in position 1: ordinal not in range(128)

I think using .decode('unicode_escape') will solve the problem, I will test it a little and make a PR, sunday ;)
