[TW-1681] parser: Cannot filter by words with slashes

% task add foo/bar
Created task 1.
% task foo/bar
[task next foo/bar]
Cannot divide real numbers by strings
zsh: exit 2

The error message is wrong: foo is not a real number.

I expected the filter to match the task I had just added.

The way to do this is:

$ task /foo\\/bar/

Moving to backlog, not sure how to address this. The presence of a workaround reduces the need.
