Minor bug in error reporting

[Former user]

When tuple is passed to query() method I get the error:

  File "sqlalchemy/orm/query.py", line 3062, in __init__
    "expected - got '%r'" % column
TypeError: not all arguments converted during string formatting

The fix is simple, just use single item tuple as right operand:

    "expected - got '%r'" % (column,)

I know why this looks familiar now, because its #2297. going to target that at 0.7.4 with a note to add for 0.6.9 as well.

Removing milestone: 0.7.4 (automated comment)
