Wrong error message and junk in the log for disabled namespace

[Kostja Osipov]

If a namespace is defined, but disabled, Tarantool reports:

tarantool> insert into t1 values ('abcd')
An error occurred: ERR_CODE_NO_SUCH_NAMESPACE, 'No namespace with specified id exists'

The error log contains more stuff than necessary:

1306534962.466 6857 107/33013/handler 127.0.0.1:50878 box.m:769 W> namespace 1 is not enabled
1306534962.466 6857 107/33013/handler 127.0.0.1:50878 box.m:96 E> tnt_BoxException: "There is no such namespace"/`namespace is not enabled' at /home/kostja/work/tarantool/mod/box/box.m:771
1306534962.467 6857 107/33013/handler 127.0.0.1:50878 box.m:1229 E> tnt_BoxException: "There is no such namespace"/`namespace is not enabled' at /home/kostja/work/tarantool/mod/box/box.m:771

- the error is already reported, first (the namespace is disabled)
- tnt_BoxException is logged twice, which is wrong
- wrong error text in the exception, the namespace is defined.

How to repeat:
Here's my namespace[1] configuration:

namespace[0].index[1].type = TREE
namespace[0].index[1].unique = 1
namespace[0].index[1].key_field[0].fieldno = 0
namespace[0].index[1].key_field[0].type = "STR"
namespace[0].index[1].key_field[1].fieldno = 0
namespace[0].index[1].key_field[1].type = "NUM"

Fixed in 1.4.2, test case in box.test

box/sql.test, that is.
