Sloeber tool selction the Arduino IDE way is working based on platform version and not tool version

[jantje]

Describe the bug
When Slober selcts the tool the "arduino IDE way" it not really uses the arduino IDE way. Arduino IDE selects the tool with the same name with the highest version.
Sloeber selects the tool with the same name installed by the platform with the same hardware and with the highest version number

To Reproduce
Steps to reproduce the behavior:

1. Add json https://adafruit.github.io/arduino-board-index/package_adafruit_index.json
2. install adafruit nfr52 platform (I tested with 0.18.5 which comes with arm-none-eabi-gcc\7-2017q4 )
   3.install arduino nfr52 (I tested with 1.0.2 which comes with arm-none-eabi-gcc\4.8.3-2014q1)
3. make sure select the arduino IDE toolchain is on
4. Create a project based on adafruit nfr52 bluefruit metro
5. The build fails

Expected behavior
The build should use 7-2017q4 (version 7.0.0 >4.8.3)

Desktop (please complete the following information):

• all oses

Additional context
The method setTheEnvironmentVariablesAddThePlatformInfo clearly selects the platform based on the platform version. but it should select the tools based on the tools version
