issue when unloading switched-off module or when loading switched-on module not reported

[xdelaruelle]

Taking the following modulefiles as example:

$ cat /path/to/modulefiles/ta
#%Module
if {[module-info mode unload]} {
    break
}
$ cat /path/to/modulefiles/tb 
#%Module
if {[module-info mode load]} {
    break
}

When switching ta by tb, ta unload fails but no error message is reported. Same situation if switched-on module fails to load, no error message is reported.

$ module load ta
$ module list
Currently Loaded Modulefiles:
 1) ta
$ module switch ta tb
$ module list
Currently Loaded Modulefiles:
 1) ta
