Add || true to .bashrc lines in case set -e is on

[gibfahn]

In the (super-rare) case that someone does something like:

set -e
. ~/.bashrc

and the nvm lines are the last two lines in the shell script, and the nvm directory doesn't exist, the bashrc will return 1 as the exit code, killing the parent shell.

To be honest I'm not sure it's worth fixing this edge case, most people who aren't writing scripts don't have set -e in their shell, and most people writing shell scripts aren't sourcing their

An alternative workaround for this is to add ; true (or ; : for maximum opacity) instead of || true), but I feel like || true is most obvious.

I tested this by doing:

▶▶▶ SOURCE_STR="\nexport NVM_DIR=\"${PROFILE_INSTALL_DIR}\"\n[ -s \"\$NVM_DIR/nvm.sh\" ] && \\. \"\$NVM_DIR/nvm.sh\" || true  # This loads nvm\n"
COMPLETION_STR="[ -s \"\$NVM_DIR/bash_completion\" ] && \\. \"\$NVM_DIR/bash_completion\" || true # This loads nvm bash_completion\n"
▶▶▶ printf "${COMPLETION_STR}"
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" || true # This loads nvm bash_completion
▶▶▶ printf "${SOURCE_STR}"

export NVM_DIR=""
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" || true  # This loads nvm

and it seems to work, I should probably test it more though.
