the version of alexandria commited to teepeedee2 doesn't work with the current babel

[avodonosov]

The function alexandria:format-sybmol in the alexandria version that comes with teepeedee2 doesn't convert it's argument to string. In result babel fails with error "value #:~A-CODE-POINT-COUNTER is not of the expected type STRING".

Note, it is necessary to rm -r ~/.cache/common-lisp to reproduce this problem reliably
