Possible erratic `rm -rf` command

[IvanGrigorik]

Main test script _run() function contains a command that may remove the whole system or files in the root directory.

acmetest/letest.sh

Lines 729 to 730 in 0bd9b5a

	rm -rf "$lehome/$TestingDomain"
	rm -rf "$lehome/$TestingDomain$ECC_SUFFIX"

The lehome variable, which was defined above, may be erratic as well, since the DEFAULT_HOME variable directory may not be created, due to the absence of the ca directory.

acmetest/letest.sh

Lines 781 to 795 in 0bd9b5a

	lehome="$DEFAULT_HOME"
	if [ -f "$lehome/$PROJECT_ENTRY" ] ; then
	$lehome/$PROJECT_ENTRY --uninstall >/dev/null 2>&1
	fi
	if [ -d $DEFAULT_HOME ] ; then
	rm -rf $DEFAULT_HOME
	fi
	#reuse ca account keys for the low acount rate limit
	if [ -d "ca" ]; then
	mkdir -p "$DEFAULT_HOME"
	cp -r ca "$DEFAULT_HOME/"
	rm -f "$DEFAULT_HOME/ca/*/ca.conf"
	fi
