`ieboilstart, adopath()` - make sure command works with `net set`

This feedback was orginally provided by Daniel Klein here.

Investigate how net set relates to the settings done in ieboilstart, adopath().

If the two features cannot be made to work together, then at least make sure that it is well documented that adopath() is cannot be used together with net set.

I was able to reproduce this problem. This example confirms that someone that has set net set ado to something else than PLUS will be able to install commands after using adopath() but the commands are not made available. See reproducible example here:

. net set ado OLDPLACE

. ieboilstart, v(14.1) adopath("C:\ado\project-ado",strict) veryquietly

. 
. * Install iefieldkit
. ssc install iefieldkit

all files already exist and are up to date.

r(199);

All these settings including net set ado do indeed reset after restarting Stata. Here is output after restarting Stata after running the code above.

* Show default setting
. sysdir
   STATA:  C:\Program Files\Stata17\
    BASE:  C:\Program Files\Stata17\ado\base\

    PLUS:  c:\ado\plus\
PERSONAL:  c:\ado\personal\
OLDPLACE:  c:\ado\

. adopath

  [2]  (SITE)      "C:\Program Files\Stata17\ado\site/"

  [6]  (OLDPLACE)  "c:\ado/"

other   (current directory)

Solution is probable to include net set ado PLUS before these lines:

ietoolkit/src/ado_files/ieboilstart.ado

Lines 103 to 106 in dfaff6e

    
                   * If strict is used, the replace plus 
        
                   sysdir set  PLUS `"`apath'"' 
        
                   adopath ++  PLUS 
        
                   adopath ++  BASE

I will test when we are done reorganizing the run folder here: #336

I will keep the minor bug label despite this is a breaking bug because the case is rare. Since the bug is possible we should address, but I do not see a reason for a hotfix release.

	* If strict is used, the replace plus
	sysdir set PLUS `"`apath'"'
	adopath ++ PLUS
	adopath ++ BASE
