Describe the bug

When entering a line beginning with a number, the next line is pre-populated with a number in an unintuitive manner.

To Reproduce
Steps to reproduce the behavior:

1. Open a note
2. Start a line of text which begins with a number, but is not a markdown list, e.g. "340g honey"
3. Type return to complete the line
4. See the next line contains a markdown list

Expected behavior

Since the text I entered doesn't contain markdown syntax, I'd expect the new line to be blank. Right now, it's pre-populated with the markdown for the next number, so typing (where <CR> is the keyboard return/enter:

340g honey<CR>

becomes:

340g honey
341. 

This is even less intuitive if there isn't a non-numeric character in the first word:

340 honey<CR>

becomes:

340 honey
35.

It looks like the PATTERN_ORDERED_LIST_ITEM and PATTERN_ORDERED_LIST_ITEM_EMPTY in https://github.com/stefan-niedermann/nextcloud-commons/blob/master/markdown/src/main/java/it/niedermann/android/markdown/MarkdownUtil.java#L48 should be:

private static final Pattern PATTERN_ORDERED_LIST_ITEM = Pattern.compile("^(\\d+)\\.\\s.+$");
private static final Pattern PATTERN_ORDERED_LIST_ITEM_EMPTY = Pattern.compile("^(\\d+)\\.\\s$");

(note the escaped . character)
