Type checking for the Symbol meta-type doesn't work properly

[mvpeterson]

Describe the bug
Want to set type Symbol for a function input argument. When I pass an argument like (This is in expression) type checking is passed, though it should not.

To Reproduce
Run the following MeTTa script

(: foo (-> Symbol Type))
(= (foo $x) $x)
!(foo (This is an expression))

Expected behavior
[(Error (This is an expression) BadType)]

Actual behavior
[(This is an expression)]

Additional context

• MeTTa version: 0.1.dev2471+ge7ba2bf.d20240419, compiled with "minimal"
• !(get-type (This is an expression)) gives [%Undefined%]

Another example of the issue:

(: foo_var (-> Variable Type))
(= (foo_var $x) (get-type $x))
!(foo_var 100) ; works, fails with type error
!(foo_var $x) ; works, returns %Undefined%
!(foo_var S) ; doesn't work, returns %Undefined%
!(foo_var (an expression)) ; doesn't work, returns %Undefined%
