Fix FEATURE_NO_ERASE chips and add test for them

Browse Source 
New check was added to `check_block_eraser` in
commit 0f389aea9e but it was not
handling FEATURE_NO_ERASE chips.

This patch fixes processing such chips and adds test to run
write and verify with dummyflasher for FEATURE_NO_ERASE chips.
