issue when accessing interop properties whose name matches builtin names

[ikappaki]

Hi,

there's an issue when accessing some object property names with interop that match builtins names, such as str "AttributeError: type object 'xyz' has no attribute 'str_'"

To reproduce

1. Open up the REPL and create an object from a class that has a property with the name str

   basilisp.user=> (def x (python/type "xyz" (python/tuple) #py {"abc" 5 "str" 6}))
   #'basilisp.user/x

2. try to access the property using interop, it errors out

   basilisp.user=> (.-str x)
   Traceback (most recent call last):
   File "C:\src\basilisp\src\basilisp\cli.py", line 447, in repl
   result = eval_str(lsrc, ctx, ns, eof)
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   File "C:\src\basilisp\src\basilisp\cli.py", line 46, in eval_str
   last = compiler.compile_and_exec_form(form, ctx, ns)
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   File "C:\src\basilisp\src\basilisp\lang\compiler\__init__.py", line 191, in compile_and_exec_form
   return getattr(ns.module, final_wrapped_name)()
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   File "<REPL Input>", line 1, in __lisp_expr___74
   AttributeError: type object 'xyz' has no attribute 'str_'

The same succeeds for abc property whose name is not the same as a builtin identifier

basilisp.user=> (.-abc x)
