parse_args fails to load during tests, simplify

[teclabat]

replace parse_args
fix a few tests

When I test, I get the following:

Looks to me as the TEA Makefile only loads one package, the rl_json, but is missing the parse_args:

PACKAGE_LOAD = "package ifneeded $(PACKAGE_NAME) $(PACKAGE_VERSION) [list apply {dir {load `cygpath -m $(PKG_LIB_FILE)` $(PACKAGE_NAME)}} `cygpath -m $(srcdir)`]"
PACKAGE_LOAD_EMBED = package\ ifneeded\ $(PACKAGE_NAME)\ $(PACKAGE_VERSION)\ [list\ apply\ {dir\ {load\ `cygpath -m $(PKG_LIB_FILE)`\ $(PACKAGE_NAME)}}\ `cygpath -m $(srcdir)`]

(but I could be terribly wrong on how all this should work together)

When I run the tests manually all tests pass:

Indeed the Makefile is using the tclsh from inside the compile directory (of the previous TCL compile), but not the tclsh where it is installed and all the packages are installed.

is now included in #55
