Include nvs_commit() on three methods (#5309)

* Include nvs_commit() on three methods

In [Preferences.cpp](https://github.com/espressif/arduino-esp32/blob/master/libraries/Preferences/src/Preferences.cpp),  the functions:
```
Preferences::clear()
Preferences::remove()
Preferences::end()
```
should be revised to include a call to 
`nvs_commit()`
as required per 
[Non-volatile storage library](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/storage/nvs_flash.html)
when using 
```
nvs_erase_all()
nvs_erase_key()
nvs_close()
```
