Why does mbed cli download a version of mbed tools in to a .temp folder if it does not find tools in the current directory?

[LiyouZhou]

I was trying to update an dependency A and I do:

cd A
mbed update

I get the following output

[mbed] Updating library "A" to latest revision in the current branch
...
[mbed] Couldn't find build tools in your program. Downloading the mbed SDK tools...

and a .temp/tools/ folder full of scripts. There seem to be no point to do this as I have tools in the mbed-os folder and .temp/tools will not be used in any case.

Is there a purpose for mbed-cli to do this?

This is for backwards compatibility with mbed 2.0 / Classic.
@LiyouZhou Can you provide more information to reproduce the issue?

mbed new myprog
cd myprog
mbed add https://developer.mbed.org/users/wim/code/TextLCD/
cd TextLCD
mbed update
ls .temp

Fixed in the latest PR. Please let me know if that's not the case.
