Many bugs in dir segment

[romkatv]

I went to optimize prompt_dir in Powerlevel10k and noticed that the code is crawling with bugs. Just from the cursory look, here are some.

Tested on master with default settings plus whatever is specified in each test case.

1.

mkdir ~/'%E%K{red}'
cd ~/'%E%K{red}'

Expected content of dir segment: ~/%E%K{red}. Actual: color mayhem.

2.

mkdir ~/~
cd ~/~

Expected content of dir segment: ~/~. Actual: ~.

3.

POWERLEVEL9K_DIR_PATH_HIGHLIGHT_BOLD=true POWERLEVEL9K_DIR_OMIT_FIRST_CHARACTER=true
mkdir ~/~
cd ~/~

Expected content of dir segment: /~. Actual: ~.

Note that with these settings we'll get /foo when we are in ~/foo. I'm assuming here this is the expected behavior of POWERLEVEL9K_DIR_OMIT_FIRST_CHARACTER although I cannot imagine why anyone would want this. What's clear is that it should be consistent between ~/foo and ~/~ but currently it isn't.

4.

POWERLEVEL9K_HOME_FOLDER_ABBREVIATION=HOME
sudo mkdir /~
cd /~

Expected content of dir segment: /~. Actual: /HOME.

I reproduced the issues on next and fixed them there. We are close to a new release, so I am closing this for now. Thanks @romkatv .
